VACCÍNÍOM, Linn, An ancient Latin name,
whether of a berry or a flower, is not satisfact
o r i ly known. Linn. 8, Or. 1, Nat. Or. Vaccinacece.
All the species of this genus are well worth cultivating,
some of them for the sake of their fruit,
some tor curiosity, and others for ornament. The
different kinds of Whortle-berry and Bilberry succeed
best in peat soil, or very sandy loam. Some of them
grow best in moist situations, and others in dry.
Those requiring the heat of the stove must receive
the same treatment as the general ity of stove plants;
and are readily increased by cuttings, planted in
sand, under a glass, in heat; they may also, like
the hardy species, be raised from root-suckers,
[ 325 3
creeping roots, trailing rooting stems, or from
seeds treated as follows:—In autumn, as soon as
the seeds are ripe, they should be sown in shallow
pans, filled with very sandy peat soil, and covered
slightly over; when about an inch high, they must
be pricked out thinly into other pans, filled with
the same kind of soil. After being well rooted in
these pans, they must be planted out in spring in
proper places, taking care to keep a ball of earth
about the roots. If hnally planted out in autumn,
the worms are apt to throw them out of the ground
d u r i n g winter. Synonymes: J. V. myrtilloides. 2.
